摘要

计划中的泛欧蜂窝数字移动无线电(DMR)系统将使用带长期预测器(RPE-LTP)的常规脉冲激励，13 kb/s编解码器。试验计划分为四个阶段:(1)全国预选试验;(2)欧洲选材试验;(3)优化试验;(4)模拟爆炸误差模式的验证和表征试验。描述了所采用的主观听力测试，并概述了RPE-LTP编解码器与数字网络其他部分的性能。对其在非语音业务(包括信息和DTMF音)中的性能也给出了一些一般指导。

Subjective performance evaluation of the RPE-LTP codec for the pan-European cellular digital mobile radio system

The planned pan-European cellular digital mobile radio (DMR) system will use a regular pulse excitation with long-term predictor (RPE-LTP), 13 kb/s codec. Four phases of experimentation were planned: (1) national preselection tests; (2) European selection tests; (3) optimization tests; and (4) verification and characterization tests with simulated burst-error patterns. The subjective listening tests adopted are described, and an outline of the performance of the RPE-LTP codec with other parts of the digital network is given. Some general guidance is also given on its performance with nonvoice services which include information and DTMF tones.<>
